This is the start of a list of things you need to do to, to get your shop up and going, there will be more but these will get you most of the way there.
As I remember more steps they will get added on.
Remember this guide is written for the shops downloaded fom this site, so yours might differ lightly. Other downloads do not have the UK settings already set up, ready to be used, in some of the files:-
First look at the last page that was displayed during the installation process and follow the "Post Installation" steps under the buttons.
Then look through every entry in the admin menu and just read every option there is in each option. In this way, when you come across a problem you will know where there is something relevant to your problem or at least know there is something in the shop admin somewhere.
These are some of the shop parameters that need setting as you go through them.
